Yes it is possible with a diamond saw in a surface grinder. However, it
is very messy and and the dust/slurry is very abrasive so the grinder
owner may say "no way". We machined a lot of ferrite many years ago
for recording heads and pretty quickly the grinders were trashed.
You need very flat and smooth mating surfaces (see a big clamp on) as
this mating changes the magnetic properties of the core by inserting an
air gap. Obvious it can be made to work since #31 clamp ons are very
effective if kept tightly closed. A tungsten carbide blade will cut
ferrite in your bandsaw but I think the cut will be so rough as to be
useless. A diamond blade in a cut off saw may work if it last long
enough without water cooling.
I think you need a bigger NEMA enclosure as any of these techniques will
cost a lot more with probably poor results.

I have a one off application where I want to get 1-2 additional 2.4 inch OD

tight squeeze inside the
nema box, and coax is already silver soldered at both ends to both
connectors. Dual silver
braids have been separated at each end of the RG-393 coax, and bonded to 7-16
Dins.
Can a type 31 2.4 inch OD core be cut clean in half....like in a bandsaw ?
I have a
vertical bandsaw with a metal cutting blade in... with 3 x speeds, 80-120-200
feet per
minute. The idea here was..IF a core can be cut in half, to place the 2 x
halves back around the
coax turns... and then either glue em back together..or perhaps use a ty-rap
around the circumference.
If cores cant be cut, I will have to disassemble the entire assy, and start
from scratch, which Id
rather not have to do, pita.
